The EBI provides access to many different types of biological databases. The following is a brief summary of the types of databases available and the tools which can be used to query these database for various biological data. [Information of the supplier]

The Biomolecular Structure and Modelling group brings together groups which derive protein structural information using crystallography or NMR, those who manage databases of structural information and analysts and modellers who examine these structures to derive principles of protein folding.

The CrossFire Beilstein database is the world's largest compilation of chemical facts. As the cornerstone database to organic chemistry, the CrossFire Beilstein database is essential for generating new leads, planning synthetic routes (including starting materials and intermediates), determining bioactivity and physical properties and ascertaining the environmental fates of compounds. ...

BRENDA is the main collection of enzyme functional data available to the scientific community. It is available free of charge for academic, non-profit users via the internet and as an in-house database for commercial users (requests to our distributor Biobase). Today, as the large international genome sequence projects are gaining a great amount of public attention and huge sequence data bases are created it becomes more and more obvious that we are very limited in our ability to access functional data for the gene products - the proteins, in particular for enzymes. Those data are inherently very difficult to collect, interpret and standardize as they are highly distributed among journals from different fields and are often subject to experimental conditions. Nevertheless a systematic collection is essential for our interpretation of the genome information and more so for possible applications of this knowledge in the fields of medicine, agriculture, etc.. Recent progress on enzyme immobilisation, enzyme production, enzyme inhibition, coenzyme regeneration and enzyme engineering has opened up fascinating new fields for the potential application of enzymes in a large range of different areas. The enzymes are classified according to the Enzyme Commission list of enzymes. Some 3500 "different" enzymes are covered. Frequently enzymes with very different properties are included under the same EC number. Although we intend to give a representative overview on the characteristics and variability of each enzyme the Handbook is not a compendium. The reader will have to go to the primary literature for more detailed information. Naturally it is not possible to cover all the numerous literature references for each enzyme (for some enzymes up to 40000) if the data representation is to be concise as is intended. The data collection is being developed into a metabolic network information system with links to Enzyme expression and regulation information. ... [Information of the supplier]

InterPro is a database of protein families, domains and functional sites in which identifiable features found in known proteins can be applied to unknown protein sequences. [Information of the supplier]

The MEROPS database is an information resource for peptidases (also termed proteases, proteinases and proteolytic enzymes) and the proteins that inhibit them. The Summary page describing a given peptidase can be reached by use of an index under its Name, MEROPS Identifier or source Organism. The Summary describes the classification and nomenclature of the peptidase and offers links to supplementary pages showing sequence identifiers, the structure if known, literature references and more. ...

The Molecular Modeling Database (MMDB) contains 3D macromolecular structures, including proteins and polynucleotides. MMDB contains over 28,000 structures and is linked to the rest of the NCBI databases, including sequences, bibliographic citations, taxonomic classifications, and sequence and structure neighbors. [Information of the supplier]

PubChem contains the chemical structures of small organic molecules and information on their biological activities. PubChem is intended to support the Molecular Libraries and Imaging component of the NIH Roadmap Initiative. PubChem's chemical structure database may be searched on the basis of descriptive terms, chemical properties, and structural similarity. When possible, PubChem's chemical structure records are linked to other NCBI databases. These include the PubMed scientific literature database, for example, and NCBI's protein 3D structure database. PubChem also contains the results of high-throughput biological screening experiments. ... [Information of the supplier]

Although several sites of metabolic processes are available to the web browser, they are generally loaded with superfluous information, much of which may not be relevant for malaria parasites. The purpose of this site was to extract the pertinent information from the universal sites and to present them in an educative and informative format. ... [Information of the supplier]
